Description

Suspension and release mechanism of counterweight body

technical field

Background technique

Electronically controlled multi-bottle water sampling devices, such as Rosette Sampler, Niskin sampling bottle or Go-Flo sampling bottle and pump are widely used water samples at present acquisition device. However, the electronically controlled water harvesting device needs to be equipped with an expensive and complex deck control system and data acquisition system, and the lowering speed of the probe needs to be determined according to the water depth on site, and the cable must be put in when using it, so it is generally used in large-scale, dynamic hydrology. Sampling is carried out on a fully equipped vessel. The Niskin sampling bottle or Go-Flo sampling bottle needs to rely on the winch in use. When the sea current is large, the inclination of the cable and the sampling bottle due to the influence of the sea current is uncontrollable, so it is easy to cause the problem of inaccurate sampling depth. and the sampling bottle collides with the ship's side easily during recovery, and it is also more complicated to hang the sampling bottle and operate the hammer. The pump is a better choice in shallower sea areas. Extend the water collection hose into the target water layer, use the pump to pump water out, and install filter components as needed, but the mechanical force of the pump will destroy the key flocs in the research. In summary, it is of great practical significance to develop an automatic return water collector that is suitable for both large-scale scientific research ships and small ships. The sampling depth can be accurately controlled and the work efficiency is high. The suspension and release mechanism of the supporting counterweight of this type of water collector is one of the key technologies. There is no report on the suspension and release mechanism that meets the needs of this type of water collector and other instruments or facilities at present.
